魅力
みりょく · miryoku · JLPT N3 · noun
appeal
🧲 魅 bewitch (has 鬼 ghost inside) + 力 power = bewitching power, charm
魅 contains the 鬼 ghost radical because it first meant a spirit that enchants people. Add 力 power and you get the power to enchant someone: charm, allure, appeal. The same 魅 appears in 魅了 (to captivate).
力 — pictograph of a plow or arm muscle
力 originated as a pictograph of an ancient plow, the main tool requiring physical exertion in early agriculture. Some scholars also see it as a flexed arm showing muscle. From this concrete image it broadened to mean 'strength, power, force, effort'.
